Frasera fastigiata (syn. Swertia fastigiata) is a species of flowering plant in the gentian family known by the common name clustered green gentian.[1] It is native to the northwestern United States, where it grows in meadows and other mountain habitat. It is a perennial herb producing a single stem which grows erect and often exceeds a meter in height. The basal leaves have oval or spoon-shaped blades up to 30 centimeters long by 10 wide. Leaves higher on the stem may be smaller and narrower. Some of the leaves have white margins. The inflorescence is a dense panicle atop the stem, sometimes interrupted into a series of clusters of flowers. Each flower has a corolla of four pointed lobes each roughly a centimeter long. They are greenish, often tinged with yellow or blue. There are four stamens tipped with large anthers and a central ovary.
The rare plant Frasera umpquaensis is often included in this species.
